Korean Institute Develops Magnesium-Air Battery

A magnesium-air battery holds five times more energy than a lithium-ion battery of equal size, and has a shorter recharging time.

The Korea Institute of Science and Technology (KIST) has developed a technology that allows electric cars to travel a distance of 800 kilometers on a full battery, the distance of a round trip from Seoul to Busan.

Korean scientists have conducted the world’s first road test of a magnesium-air battery vehicle. A magnesium-air fuel cell uses a magnesium anode and oxygen from air as a cathode. This can run a mid-to-large power system with high energy density demands, such as electric vehicles or emergency power sources.
